I took a look at Triadelphia Reservoir this afternoon at Brighton Dam (B) and the mouth of Pigtail Branch (P). Most of the birds seen from the dam were along the Montgomery shore. The birds at Pigtail were in the middle of the lake and being moved around by fishermen's boats. Small flocks of birds were at each site:

Bufflehead  8 (B) + 13 (P) = 21
Hooded Merganser  4 (B) all females
Ruddy Duck  12 (P)
Pied-billed Grebe  2 (B)
Coot  2 (B) + 15 (P) = 17
Ring-billed Gull  1 (B) + 3 (P) = 4

  Along the trail at Pigtail (Howard Co.) were:

GC Kinglet  4
RC Kinglet  2
Black-throated Blue Warbler  1 male, the latest I have ever seen
Myrtle Warbler  3
Yellow Palm Warbler  1
Junco  2
